Fouling detection

Fouling or accumulation of undesirable materials can damage machine parts and plants. gSKINgt sensors can provide sustainable protection for sensitive infrastructure.

Heat flux sensing technology can be used to perform fouling detection for a broad range of research and industrial applications


As layers of undesirable materials form, the absolute thermal resistance of the component or element in question increases. Heat flux measurements can help detect these conditions before they lead to damage and costly repairs.

Measurements in studies show that absolute thermal resistance increases as soon as contaminants appear and form a layer – a bacterial film on a fin heat exchanger, for instance.

gSKINgt sensor technology can measure temperature and heat flux. This allows for analysis of absolute thermal resistance as a means of detecting contaminants.

innogt technology extends into many other exciting areas of application, including the aviation industry (e.g. detection of ice build-up on airplane wings), shipping (detection of algae build-up) and medical technology (warning system for bacterial build-up).


gSKINgt sensor technology for measuring thermal resistance in pipelines, boilers, plants and infrastructures.

With the gSKIN® DLOG data logger, innogt technology enables simple data analysis via certain devices or PC.
